Kinetic characteristics of cylindrical moving coil linear DC motor for vibrator

A cylindrical moving coil linear DC motor has been developed for a vibrator which is driven at high frequency and at short stroke. The actuator is supposed to be driven using the resonance of spring plates which are equipped at the end of permanent magnet and armature. This paper describes the investigation of the motor stroke to frequency characteristics and stroke to pulse duty characteristics as regards the kinetic characteristics of the actuator.
